We’ve been rocking the one key given to us when we bought this RX 5-6 years ago but I want to get some spares.

Called Lexus and they quote $350 for pairing a new key with the car.

I’ve seen relatively straightforward methods for pairing new keys - essentially locking/unlocking the master door switch multiple times in an ordered procession. So I am thinking about buying a spare key from lexusparts.com and pairing them myself. Is there something I am missing about pairing more keys that justifies $350?

 

First confirm that you have a master key in procession.

The cost should be key blank
Electronics
personalization of the key [cutting]
Programming cost. [Should be 1/2 hr at Lexus rates ... and if they include the cutting the charge may go up to 1 hr]

Programming steps us listed in this Forum. You can look under DIY sticky thread.

I purchased a replacement master key on eBay for $48.09, had a mobile locksmith meet me at our Toyota dealership in Madison, IN after hours and he cut it in his van while I waited ($25). I programmed it myself using the instructions on this forum.
The master key is the big black one that includes the remote control mechanism. The grey key is a valet key and I don't believe you can use that to program a master key, of course you may know this already.

 

Fit1too ... what about the electronics ... was that included in the ebay key? Or you had that from an old key.

Yes that is for everything. I pulled up the info from my old eBay purchases and their price has gone up $20. It states in the ad, "100% genuine OEM circuit board/button pad/transponder in a new aftermarket case”. Mine has been working fine for well over a year now.

 

I took a picture of the ad, but don't know if the forum allows that sort of thing. If so, I'll post it.

 

If OP wants it he can use Private mail and communicate directly with you.

Thanks
